In February, discussion about AlderLake CPU were in -current ML, starting from [1] and disabling pcid was proposed by kib@ at [2]. Looking sysctl descrintion, I "feel" this can affect P- core only AlderLake, too. % sysctl -d vm.pmap.pcid_enabled vm.pmap.pcid_enabled: Is TLB Context ID enabled ? For example, it was 1 on Intel(R) Core(TM) i7-8750H CPU (Coffee Lake) and on board Intel(R) I219-V CNP(7) is working as em0. FreeBSD 13.1-STABLE #460 stable/13-n250911-b92a06875045-dirty, amd64. So if I didn't miss any AlderLake-related commit, this would be 1 on AlderLake, too.
